You can do an upper and lower bound by inscribing and circumscribing polygons. The more sides the polygon has, the more precise your answer will be. You inscribe a polygon by having the corners touch the circle's interior, and you circumscribe a polygon by having the midpoint of the sides touch the circle's exterior. Note that the polygon must by equilateral and equiangular for this method to be reasonably simple. Then simply find the area of the inscribed polygon - you know the circle is bigger than it, because the circle contains the polygon and has more space as well. Thus that number is your lower bound. Then find the area of the circumscribed polygon- same logic for the polygon being bigger than the circle. Area of circumscribed is your upper bound. Then typically average your upper and lower bound to get a reasonable estimate of the area of the circle. Of course, solving the problem algebraically is both simpler and more precise, but since you wanted a geometric answer, you got one.

Can area of a circle be represent as area of a rectangle?
Yes, the area of a circle can be represented in a rectangular form using the formula for the area of a circle, (A = \pi r^2). If you imagine unrolling the circle into a rectangle, you can think of it as approximating the circle with a series of infinitesimally thin rectangles, where the height of each rectangle corresponds to the radius and the width corresponds to a segment of the circle's circumference. While the circle and rectangle are geometrically different, the area can be calculated and compared using similar mathematical principles.

How do you find the area of a circle outside a square?
To find the area of a circle outside a square, first calculate the area of the circle using the formula ( A_{circle} = \pi r^2 ), where ( r ) is the radius of the circle. Next, find the area of the square using ( A_{square} = s^2 ), where ( s ) is the side length of the square. Finally, subtract the area of the square from the area of the circle: ( A_{outside} = A_{circle} - A_{square} ). If the circle is completely outside the square, the area outside is simply the area of the circle.
